After Anzick: Reconciling New Genomic Data and Models with the Archaeological Evidence for Peopling of the Americas

Part of: Society for American Archaeology 81st Annual Meeting, Orlando, FL (2016)

The past two years have witnessed the publication of a series of ancient genomes that illuminate the peopling of the Americas: the Anzick infant, the Malt’a boy, and Kennewick Man. Along with similar data from later Holocene skeletal samples and extant Native American populations, these genomes show that a single small but diverse founder group, ancestral to all Native populations south of the Arctic, left Siberia after 23,000 cal BP and crossed Beringia about 15,000 cal BP. Is it possible to reconcile the new genomic data with putative evidence of pre-Clovis or non-Clovis archaeological cultures south of the ice sheets before 14,500 cal BP? Can archaeological and genomic data be unified into a consilient model of the peopling process?
